SPECIFICATION forming part of Letters Patent No. 460,229, dated September 29, 1891,

Application tiled January 29, 1891- Serial No. 379,484. (No model.)

T0 all whom t may concern:

Be it known that I, SAMUEL E. BRICKNELL, a citizen of the United States of America, residing at Oregon, in the county of Ogle and State of Illinois, have invented certain new and useful Improvements in IIame-Tugs, of

v which the following is a specification.

Hy invention relates to certain improvements upon hame-tugs of the class fully described in my application for Letters Patent of the United States filed on October 29, 1890, Serial No. 369,70), the desirability for which has been suggested in the practical use of the hame-tug described in said application.

These improvements are illustrated in the accompanying drawings, wherein- Figure l is a side view of a haine-tug, illustratin g certain ofmy new improvements. Fig. 2 is a top View, partly in section, of the same. Fig. 3 is a detail view of the end of the-tug and the hook attached thereto. Fig. 4t is a section taken in lineeL 4 of Fig. 3. Fig. 5 is a side View of a haine-tug, showing certain additional improvements. Fig. 6 is a broken section cut in line 6 6 of Fig. 5; and Figs. 7, S, 9, and l0 are perspective views of certain details of construction.

The general features of the construction here shown are old and are fully described in myprior application. They consist of a hame A, having a yoke-shaped plate C bolted to it by bolts B, a block C', pivoted within the yoke C by a horizontal bolt B, a box F, containing holes fin one side, a link D, vertically pivoted to the block C and also to the box F, and a tug G, having at its end a pivoted hook Il, the undercut head h of which is pressed by a spring S into the openings f.

My rst improvement relates to the spring S, which tends to force the head h into the openings f. I find that when the tug and the hook upon its end are removed entirely from the box and possibly thrown upon the floor the end s of the spring S swings so far from the hook under the torsion of the coiled spring thatif anything happens to be thrown upon it or if it is stepped upon it is bent backward still farther and sometimes broken. To prevent this I have added a device adapted to prevent the free end of the spring from swinging backward any farther thanis necessary to give the hook tho required amount of play. It is of course immaterial what particular device is employed for this purpose, as any mechanic could doubtless construct a great number which would be equally satisfactory; but the best which I have tried consists of a plate K, arranged behind the spring and pivoted at one end upon the arbor thereof by means of tongues 7c, turned up from said plate. The amount of play is fixed byconstructing the tongues It so that they will strike against thehook H, as shown in the drawings. It is obvious, of course, that the port-ion k of the plate itself could be allowed to strike against said hook. 'This improvement keeps v the end sof the spring' in such a position that, no difference what falls upon it, it can only be forced down against the hook H but little beyond the position which it occupies when in the box F.

My second improvement is in the manner of pivoting the hook H to the tug G. This is done by means of a plate I, sharpened at the end t', so that it can be driven into the end of the tug and secured thereto by rivets g, and having at the opposite end a hook t', adapted to receive and hold the round portion h of the hook I-I. The open part of the hook is not large enough to allow this round portion to be slipped therefrom; butat one edge said hook II is reduced in size at 7b2, so that by turning the hook backward until this reduced portion is above the open part of the hook z" it can be slipped downward through said open part and the hooks disengaged from each other.

My third improvement relates to the universal-joint connection between the box F and the hame A, and is designed at once to simplify said connection, to enable lthe different parts included therein to be easily and readily taken apart, and to make the portions where the greatest wear occurs separable, so that when they are worn out they can be removed and replaced by new pieces of uniform size kept in stock by the dealer and readily applied when needed with but slight trouble and expense. Said connection consists in a clevis-shaped link D, (see Fig. 7,) pivoted directly to the box F by means of a pin d and having the block C pivoted upon its side opposite to said pin. To enable said block to be readily removed from the clevis ICO the middle portion thereof in front of the clevis is made in the shape of a separate piece c, (see Fig. 9,) so that it can be removed when the bolt B is taken out. As a further improvement the portion of the block C about the hole through which the bolt B passes is also made in a sepa-rate piece c', (see Fig. 10,) which can be removed and replaced with a new piece as the bolt B wears it away, and which also serves to hold the part c in place when the bolt B is removed.

To adapt my improvements, both as heretofore described and as now modified, to what is known as a long llame-tug,7 I have interposed between the box F and thelink D a second box F', made of the same general appearance as the box F, but lacking, of course, the fea-tures of the latter which adaptit to engagement with the tug. The two boxes are hinged together by means of links L L and pins passing through the ends of said links and the two boxes. The box F has brackets f secured to it above and below to enable the belly-band and the back-band to be secured thereto, and the lengths of the two boxes are so proportioned that when the two fold to* gether upon their hinged connection the haines and said bands shall fall together and the entire harness be in compact form, so that it may be hung up in the least possible space.

I do not of course limit myself to the combination of all the different improvements above described, as it is evident that they can be used either conjointly or separately.

The different combinations which I believe to be new, and desire tov secure by Letters Patent, are as follows:

l. The combination of a tug G, a hook I, secured to the end thereof, having an open head i', a second hook Il, having a portion -'L iitte'd to the interior of the head i of the hook I and having an adjacent portion h2 reduced suficientl y to slide through the opening` in the head i', substantially as described.

2. The combination of a tug, a hook I, having a shank sharpened at fi, suitably secured to the tug, and an open head t', and a hook H, having a round portion 7L Iitted to the interior of the head and an adjacent reduced portion h2, adapted to slide through the opening thereof, substantially as described.

3. The combination of a tug, a link secured by suitable devices to the end thereof, a block C', pivoted upon said link and having the removable piece c, and a pivotal connection between said block and the other portions of the harness adapted to hold the portion c in place, substantially as described.

4. The combination of a tug, a link D, suit- I ably secured to one end thereof, a block C', pivoted upon said link and having the separable portions c and c', and a pivot B', passing through the latter and suitably connected with the other portionsof the harness, substantially as described.

5. The combination of a tug, a box F, adjustably secu red to the end thereof, a clevisshaped link D, pivoted to one end of the box by means of a pin CZ, a block C', pivoted upon the link and containing the separable portions c c', a haine, a yoke C, secured thereto, and a pivot B', passing through the yoke and the portion c of the block C', substantially as described.
